Abstract: MEAT CLEANING MACHINE                 Abstract of the Disclosure A meat cleaning machine having an improved meat driving cylinder which includes a series of concentrically arranged, axially spaced, meat driving rings having outwardly projecting teeth which define the outer surface of the cylinder, and a supporting framework which consists of a pair of ring-shaped end frames positioned axially outwardly of the meat driving rings and interconnected by a pair of cross members disposed outwardly of the periphery of the cylinder.   Each end frame has a pair of spaced, outwardly opening slots and a single inwardly opening slot.  The slots in each end frame are aligned and form seats to journal the ends of grooved rollers which receive the meat driving rings in their grooves to support them, space them axially of the cylinder and maintain them in concentric relationship to each other. Because of the inherent rigidity of the supporting framework as opposed to prior art structures of cantilevered design, the framework can be made of lighter construction while still providing increased rigidity with respect to the cantilevered design and improved ease of assembly and disassembly as well as freedom from interior cross members.

Abstract: METERING ROD CONTROL FOR AN AIR VALVE CARBURETOR      Abstract of the Disclosure An air valve for a carburetor has its lower end mounted for pivotal movement between open and closed positions relative to the air and fuel mixture conduit and carries a metering rod which extends generally in a horizontal direction.  The metering rod has an end extending within a metering orifice of an orifice plate in an opening of the mixture conduit wall.  The metering rod is urged by a coiled torsion spring upwardly against the orifice plate.  The torsion spring has a small coil with a relatively high spring rate and a large coil with a relatively low spring rate.  The large coil continuously urges the rod into engagement with the upper surface of the orifice plate defining the orifice, while the small coil urges the rod into engagement with the orifice plate only after the air valve is around one-half open.  The metering rod is mounted for limited pivotal movement relative to the air valve and the torsion spring exerts a generally uniform light force to the metering rod throughout the longitudinal movement of the metering rod to compensate for the varying distance between the orifice plate and pivotal mounting of the metering rod and the increased load against the rod caused by impinging air flow.

Abstract: ABSTRACT OF THE DISCLOSURE          A filtration system for removing both large, bulky and small, compactible solid contaminants from a liquid, intended primarily for the collection of chips and purifying and recycling coolant liquids used in machining and other metal working operations.  Contaminanted liquid which has been used in the machining operation transports metal chips and other contaminants to a tank divided into upper and lower compartments by a wedgewire strainer.  The sub-atmospheric pressure which develops in the lower compartment due to pumping of clean liquid from the lower compartment and the build-up of small, compactible contaminants on the upper side of the strainer is measured and a signal commensurate with the magnitude of the pressure provides the input to a drive motor for a continuous loop drag conveyor which scrapes the ships and sludge from the surface of the strainer. Thus, the rate of chip and sludge removal and the degree of coolant clarity is continuously and directly proportional to the degree of contaminant build-up.  Also, the input signal to the drive motor has a minimum value greater than zero which is established as a function of the volumetric rate at which large, bulky contaminants, such as curly metal turnings, are supplied to the upper compartment.  Although these contaminants provide very little resistance to flow through the strainer, they are none-theless removed from the tank even at times when little or no small, compactible contaminants are present to increase the pressure differential between the upper and lower compartments.

Abstract: ABSTRACT OF THE DISCLOSURE           A system for the excitation and mapping of natural gases at the earth's surface in which the atom to atom bond within non-polar gases is electrically disturbed to polarize them and rotate them at a resonance frequency uniquely determined by the molecular movement of inertia and angular momentum and in which the excitation frequency band is separate from the emission frequency band, without overlays.  The molecular moment of inertia and angular momentum identifies the gas chemically as it is not a characteristic of chemically different molecules.  A detector resolves and measures the exicted emissions from the gases and rejects energy reflected from hard targets contained in the excitation energy frequency band.

Title: Coal hydrogenation catalyst recycle
Inventor: MOLL NORMAN G
IPC: C10G1/06
Filed: 1978-02-27
Granted: 1981-08-18
Abstract: A B S T R A C T     The present invention resides in the field of the catalytic hydrogenation of coal.  The invention is a process for recovering and recycling a substantial proportion of the catalyst used in the hydrogenation of coal, where the coal is slurried in recycle oil in the presence of the suspended catalyst.  The catalyst is of a significantly smaller particle size than the ash particles from the coal, the hydrogenated slurry is separated by gravity concentra-tion, thus concentrating the ash particles in a lower layer and a substantial portion of the finer catalyst particles in the supernatant oil, and at least part of the oil is recycled to the hydrogenation process.       The principal advantage is that only small amounts of fresh catalyst must be added to the coal slurry make-up to retain the original catalyst level. 18,293-F

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to drive mechanisms  for equipment to be intermittently operated.  Known intermittent drive mechanisms are limited in speed capacities so that desirably high production cannot be realized.  Moreover, such known mechanisms exhibit undesired lack of uniformity of intermittent movements, and hence of output results.  Still further, such mechanisms are undesirably complex and are characterized by inordinate down time of equipment.  The present invention overcomes the deficiencies noted above by providing an apparatus having a control shaft extending through and rotatable in a housing parallel to a stub shaft therein which has one end extending through one wall thereof. Within the housing are four bevel gears, one being keyed or fixed to the control shaft, a second rotatable on and relative to the control shaft, and the remaining two meshing with the first and second ones and carried on a block that is rotatable on and relative to the control shaft.  The second bevel gear is keyed to the larger of  a pair of meshing spur gears, such larger gear being rotatable relative to the control shaft and the smaller spur gear being fixed to the stub shaft. Respective discs are fixed on the adjacent ends of the two shafts, and articulated holding devices are operable to alternately hold and release the discs.  An external arm adjacent the other end of the control shaft Is coupled through the housing to the block.

Abstract: Abstract A refractory burner block having a generally cup shaped depression is adapted for mounting in a, furnace wall, with the depression facing the furnace interior.  The block is provided with a bore that extends from the cup shaped depression to accommodate a burner nozzle.  Resilient means con-nect the burner block with the cover plate so that both block and cover plate may independently contract and expand, minimizing stress loads on the cup, resulting in less cup cracking and failure.  A joint is provided with a step between the furnace wall and the burner block, reducing the possibi-lity of gaps opening up and forming a barrier to radiant heat and to con-vection flow.  A central locating collar relieves the anchor bolts from undue stress in supporting the burner block.  A resilient seal is used to seal the block against the central locating collar.  Pilot means to light the main burner and plenum means to buffer the pilot from the main burner are provided to reduce pilot "blowout".

Abstract: METHOD AND APPARATUS FOR PULSED NEUTRON SPECTRAL ANALYSIS USING SPECTRAL STRIPPING     Abstract of the Disclosure.  A pulsed neutron generator in a well logging instrument is pulsed at a clock frequency of 20 KHz.  Inelastic scatter gamma rays are detected during a first time interval coinciding with the neutron source being on and capture gamma rays are measured during a second interval subse-quent to the end of each neutron burst.  Only a single detected pulse, assuming detection occurs, is transmitted during each of the two detection intervals.  Sync pulses are generated in the well logging instrument scaled down to a frequency of 230 Hz for transmission to the earth's surface.  At the earth's surface, the scaled-down sync pulses are applied to a phase-locked loop system for regenerating the sync pulses to the same frequency as that of the clock frequency used to pulse the neutron source and to open the detection gates in the borehole instrument.  The regenerated sync pulses are used in the surface instrumentation to route the pulses occurring In the inelastic interval into one section of a multichannel analyzer memory and the pulses occurring in the cap-ture interval into another section of the multichannel analyzer.          The use of memory address decoders, subtractors and ratio cir-cuits enables both a carbon/oxygen ratio and a silicon/calcium ratio to be struck substantially free of background radiation and substantially unaffected by downscattering of high energy gamma rays.                             -1a-
